Hey, Anybody care to help out us laymen who dont speak computer language, on the subject of loading PTT onto a tmoobile pearl running on cingular? I tried JIBI's instructions but couldnt figure it out for the life of me. Please can somebody give clear and detailed instructions (make believe you are explaining it to your 14 year old (before the myspace age)

Yes you can, I did it along with a few others that I know of for sure.

The way I did it was to upgrade my OS at the same time. I feel that makes it easier.

There is a thread that has a ton of modified ALX files for all different devices. It also has links to the OS upgrades.

I simply downloaded the updated OS files, installed them on my PC, then downloaded the modified BlackBerry.alx and Platform.alx files from the thread. Once thats done, all you have to do is replace those two files in the installation directory of the upgraded OS on your PC.

Plug the device in, it should upgrade your OS, and install the PTT modules.

You should call Cingluar prior to the upgrade and have PTT added to your account. Its $4.99/month for 500 PTT mins, and $9.99/month for unlimited PTT.

After the upgrade, you should see the PTT app in your list. The first time you run it, it should initialize. Once thats done, you just add PTT contacts by mobile number. If they have a PTT enabled phone, it will add them, if they do not, it will error out.

Those two files will already exist in the directory above, you simply need to drag and drop the ones from the blackberry.zip file into this directory.

As far as which OS to use, I used the newest one (Telefonica) and it works great.

I replaced the files, one last question, I cant seem to find how to update the device software to the .67 that i just customized, or any .67 for that matter. Its in the bb desktop manager but there is no update button how do i transfer this software to my device?

Disconnect the 8100 from the PC. Now, on the PC find and delete the vendor.xml file. Then re-connect the 8100. It should automatically ask you if you want to upgrade.
